ATTORNEY Patented Apr. 20, 1954 U NITED S PATENT OFF-ICE 2,875,867 7 "POT TYPE OIL BURNER V --Jbsej'ph rivtnhhh, Huntington Mills, Pa.

Application januaryl l, 1948, Serial No. 2,287 2 Claims. (01.15841) The invention has for its obj'ect's:

To provide a means 'for efficientlyburnii1g light and heavy oils, tars and similar petroleum products. 7

To provide a heater for orchardist's use in preventing frost damaging the fruit trees.

'To provide a burner for use in furnaces having an electrical-ignition system.

To provide a burner for the above purposes which will not clog or choke up with carbon.

To provide a burner for the above purposes which will be quite inexpensive to build "and will eifectively serve its intended purposes. 7

' To the attainment of the aforesaid objects and ends invention still further resides in the novel details of construction, combination and arrangement of parts, allof which will be first fully described in the following detailed de* scription, and then be particularly pointedout in the appended claims, reference being had to the accompanying drawing, in which:

Fig. 1 is a central vertical section, parts being in elevation, on the line I-I of Fig. 2.

Fig. 2 is a top plan view of the same.

Fig. 3 is a view similar to Fig. 1 showing a modification of the burner shown in Fig. 1.

Fig. 4 is a top plan view of another modification of the invention.

Fig. 5 is a side elevation of the same.

Fig. 6 is a cross section on the line 66 of Fig. 4.

In the drawings like numerals and letters of reference indicate like parts in all the figures.

In Figs. 1 and 2 I have illustrated the embodiment of my invention that is especially adapted as an orchard heater and by reference to these figures it will be seen that a suitable base I is mounted on leveling legs I9 and supports an outer shell 4 that supports a topring plate I3 having, preferably, a downwardly-inwardly directed flange I2 that serves as an air bafiie.

Within and spaced from the walls of the shell 4 is an oil pot 5, having an oil admitting elblow 6 which is connected to a supply pipe I6 and which is laterally adjustably supported on a vertically adjustable support 9 having, if desired a recess 8 for a guide or lateral adjustment limiting pin 1 on the elbow 6. The support 9is adjustable by means of a threaded collar I0 which is swivelly mounted on the base I. The pipe I6 also has a collar I6 to close off air escape through a hole l through which the oil pipe I6 passes.

The oil pot is laterally adjusted so as to center its mouth with the ring plates flange or lip I2,

2 by-means of adjusting screws I I mounted on the wall of theshelld. g p I v Air for supporting combustion is admitted to the shell :4 via a duct 2, the, entrance to which is controlled by a damper 3 that may be held in open position by means of a rack 20 and -pin 3f.

, Mounted on the {3131:1643 is a flanged member I4 having an opening I5 to permit the flame generated by the combustion of oil pot5 to pass freely. The member I4 maysupport a pipe .section or sections serving as a flue when it is desired to carry the products of combustion higher than the bu-rner before releasing the products to atmosphere. x ,7 v

I! is a liquid seal cup on the inlet end o'fpil pipe It to receive the neck cf an inverted bottle of oil I8 to supply fuel to the cup II and :2I indicates a SupI QIting saddle for pipe -I 6, etc.

In operating the present embodiment of my invention the oil in ot 5 is ignited in any suitable way .as, for example, by burning some paper on top of the oil in the pot, if the oil too heavy to ignite by the simple application of a match. Of course, the pot 5 is first adjusted to center it and bring its upper edge to such position adjacent the plate I3 as to leave an air pass of pro er dimension over said upper edge (see arrows Fig. 1). Damper 3 is opened sufliciently to give the desired combustion (smoke smudge or clear combustion) In Fig. 3 is shown a modification of the burner shown in Figs. 1 and 2, which modified burner is particularly adapted for use in the fire pot of a furnace where thermostat draft regulation and electric ignition is provided for. In this embodiment those parts which correspond to like parts in the preceding figures bear the same reference numbers plus the index letter a. and need not be further described here.

In Fig. 3, 32 designates. a spark plug having ignition points 33, and a float controlled valve 23 governs the supply of fuel oil to the oil pot 5* from an oil tank 25.

The float valve control in the embodiment shown in Figure 3 is located in a float box'22 into which the oil is delivered by valve 23 under control of a float lever 24. The oil from tank 25 is delivered to valve 23 by a pipe 26 and from the box 22 to the burner pot 5 by the pipe I6. The damper 3 is regulated by a cable and pulley arrangement 21 from a thermostat controlled damper operator (not shown) of any approved construction the same thermostat also controlling the action of the ignition if desired. The flame may be extinguished, when desired, manually or by a cover such as is shown, for instance, at 280 in Fig. 6 and controlled in a similar manner.

In Figs. 4 to 6, inclusive, is shown another modification of the invention which has been especially designed for use in furnaces having elongated fire pots and provided with electric ignition systems. In these figures those parts which correspond to similar parts in the preceding figures bear the same reference numbers plus the index letter 0.

A lid 280 is hinged to the top plate 130 and is fastened to a hinge pin 290 which is operated, in any suitable way to open and close the lid accordingly as the main burner is to function or not, as, for example, by a pulley 30c suitably operated by a thermostatically controlled damperoperating motor (not shown).

Air is forced through the air duct 20. A fan 210 whose impeller is driven by a suitably controlled motor tile is indicated in Fig. 4.

The burner of my invention will eliminate the danger of explosions caused by the accumulation of unburned gases and oils that are forced into the furnace by present oil fumes should ignition or sparking equipment fail. With my burner I do not use force to blow the oil, hence there can be no accumulation of oil when the burner is not burning.

The several embodiments above described can preferably all be made of sheet metal or boiler plate.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, operation and advantages of the invention will readily appear to those skilled in the art.

What I claim is:

1. A burner including an outer shell enclosing an imperforate oil pot, a vertical supporting post adjustably secured to said shell and having a guide-pin recess in its upper end, an oil pot elbow carried by said oil pot and having a guidepin to operate in said guide-pin recess, said elbow resting on said vertical post, adjusting screws carried by said outer shell and engaging said oil pot for adjusting the same laterally, said shell having a top plate with an opening through which products of combustion pass upwardly, and means for supplying oil through said elbow to said oil pot.

2. A burner including an outer shell enclosing an imperforate oil pot, a vertical supporting post adjustably secured to said shell and having a guide-pin recess in its upper end, an oil pot elbow carried by said oil pot and having a guide-pin to operate in said guide-pin recess, said elbow resting on said vertical post, adjusting screws carried by said outer shell and engaging said oil pot for adjusting the same laterally, said shell having a top plate with an opening through which products of combustion pass upwardly, an means for supplying oil through said elbow to saig oil pot, the opening of said top plate being of less diameter than the opening of said oil pot.
